Grep.pm is a much-modified fork of tcgrep. It understands context, matching from the start or end of a file (with a line count or byte count), and features size limits and highlighting. It extends matching to boolean expressions, structuring regular expressions, or even arbitrary pieces of Perl code. It can perform basic stemming and synonym-expansion in regular expressions (using expansyn). It also handles \0-lines, paragraphs, file slurping, directory recursion, and compressed files. It can act either as a Perl module or a command-line program. Grep.xchange is a support program taking grep or Grep.pm input and applying an expression at each grep match to the files specified in the grep output. This expression can be arbitrary Perl modifying e.g. just the line of the match with s///g, or operate against the current pos() position in the whole file. Grep.xchange --modified goes one step further and replaces the matched lines with the (edited) text from the grep output. Changes are logged in diff -u format and can be revoked/redone with patch.

IgnoFlash is a patch that modifies the Adobe Flash Player plugins for Netscape and ActiveX to keep them in fullscreen when focus is lost. It makes it possible to operate another application when watching Flash video in fullscreen on a multi-monitor setup. You can still close fullscreen with the usual methods (Escape key, UI elements). This patch has been tested with Flash Player versions 10.0 and 10.1 in Opera, Firefox, Chrome, and Internet Explorer. It might also work for previous and future versions.

Xmlpatch is a simple utility to change XML files. It takes a patch file containing a list of changes and applies them to the files specified in the patch file or on the command line. Its command line interface is similar to the well known patch utility.

Darning is a tool for managing a series or sequence of patches to a software source tree, in the same vein as quilt but with extended functionality. It supports advanced patch concepts such as file mode changes and copying/renaming files. The GUI is the primary interface and the most complete, but a command line interface is also provided with fewer features at this stage.

SafePatch lets you edit program files and track those changes creating "patches" which can later be reverted or reused in a different setup. It's written in PHP, but can patch non-PHP applications because no integration into their source code is required. A bundled Control Panel allows easy tracking, installing, reverting, and diffing of available patches. SafePatch has an intuitive text patch file syntax which is uniform for text and binary files and independent of the engine being patched, has default support for VQMod .xml patches and FluxBB README mods, is written in OOP and uses events (and thus is easily extensible), and doesn't need a database.

The X3D library is used to load an X3D file and render it using OpenGL (an X3D file is an XML file describing a 3D environment that can be rendered with OpenGL.)
The library supports all the objects as defined in the X3D specification in 2006. The render library is still somewhat limited, though. It works well under Linux. It is likely to work on any Unix, and has worked under MS Windows before. The project includes a test that makes use of FLTK version 2.0-m3. That version of FLTK can be downloaded from the project repository, as FLTK itself actually ended up not publishing a concrete 2.0 version of the library.

JSON-delta is a multi-language software suite for computing deltas between JSON-serialized data structures and applying those deltas as patches. It enables separate programs at either end of a
communications channel (e.g. client and server over HTTP, or two processes talking to one another using bidirectional IPC) to manipulate a data structure while minimizing communications overhead. Robust reference implementations are available in Python and Javascript. Work is ongoing on other implementations, including Racket and Perl.
